A) \[{{i}_{2}}>{{i}_{3}}>{{i}_{1}}\]
B) \[{{i}_{2}}>{{i}_{1}}>{{i}_{3}}\]
C) \[{{i}_{1}}>{{i}_{2}}>{{i}_{3}}\]
D) \[{{i}_{1}}>{{i}_{3}}>{{i}_{2}}\]
Correct Answer: A
Solution :
Just before closing the switch \[{{i}_{1}}=\theta ,\,\,{{i}_{2}}=\frac{E}{R}\,\,,\,\,{{i}_{3}}=\frac{E}{2R}\] So, \[{{i}_{2}}>{{i}_{3}}>{{i}_{1}}\] After a long time closing the switch \[{{R}_{eq}}\,=2R,\,\,{{R}_{eq}}\,=\frac{R}{2}\] \[{{R}_{eq}}=R\] Hence \[{{i}_{2}}>{{i}_{3}}>{{i}_{1}}\]You need to login to perform this action.
